For the full use of the tube performance and materials save, it is not advised to useφ22mm suck rod string as the second level.
Calculation results show: the weighting rod is beneficial for reducing the number of the centralizer but causes the increases of friction force for each centralizer; the suck rod can be well evaluated in tow aspects of material strength and performance.

The step-fault belt consisted of multiple-order concordant faults towards the sag centre, which constituted a multistage transportation path for detrital materials.
The supply of source material was abundant, and the sand grains could be transported further toward the lake center.
